If you want to use an automated service, then WordPress has restored a lot of options for you.

Here we will thoroughly discuss these basic two modes along with an alternate mode of image optimization.

Image Optimization In WordPress

1. Manual Image Optimization

Manual optimizing needs a lot of effort. Here we will discuss the most generous tactics.

Use the appropriate Image Format

There are no hard and fast rules on the right image format. But we can suggest the following formats considering the content people use.

  • JPG

JPG is a convenient choice for photographers and bloggers. This format can be easily compressed because it is adapted to lossy compression. It can preserve good quality in naked eyes after compression.JPG formats are good at holding numerous colors as well. This format is well suited to the photographs.

  • PNG

PNG formats hold lossless compression, which means your image will not lose a single attribute after going through compression. This format goes well with photographs, graphics, icons designs, sketches, etc. you can easily edit this format in simple editors.

  • WebP

This format is rendered as an alternative to JPG and PNG. The best part about this Webp is it requires minimum space. The file size is really small. Google says Webp can get minimized up to 34% than JPG and 26% than PNG. But this format doesn’t fit all browsers.

2. Figure out the Maximum Display Size of Your Image

Figure out the Maximum Display Size of Your Image

When you are optimizing manually, you must know the maximum image display capacity of your webpage. This will lead you to the further extent of image optimization. To know the maximum display capacity, please do the following steps:

Step 1: First, open a page that contains photographs. Then resize the browser manually to the breakdown point.
Step 2: Now, the image holds the larger dimension. Scroll over the image URL on the top-right screen, and you will see the dimension it is serving and the original size it holds. The former one is the maximum display capacity of your image.

3. Resize and Crop Your Image

Resize and Crop Your Image

Suppose your image size feels like a lot more to handle; you can resize or crop the photograph. This will slightly decrease the size and facilitate the page speed. If your site is all about photography, it’s certain that you have to showcase your real work. In this case, resizing is a great option.

4. Try Image Compression

 Try Image Compression

Image compression is considered one of the most common tricks in manual image optimization. It’s not mandatory to post 100 photographs of 100% quality. You can use simple tools to compress this rate up to 70-80%. This reduction is termed as optimum, which preserves both quality and quantity at the same time.

Image Optimization through Plug-ins

Plug-ins are considered automated optimization. In order to do that, you will have to select the best tools. Here we recommend the best image optimization tools in terms of solid features.

Optimole is an incredible example of perfection. This plug-in offers smart optimization than most regular plug-ins. When you install this plug-in, it will transfer the required image to the cloud storage, where it gets optimized. Then these images are sifted through CDN promptly. Each URL is replaced with a custom one. 

The best feature of this smart optimization is that it works on the requested images only. It doesn’t matter how many photographs you have loaded on your site. It will only work on the required images. So don’t get upset if you don’t see any significant changes in overall images.

This plug-in is one of the organized systems we have. You can see through every action you are going through on the dashboard. The drawback of this plug-in is it offers limited service in the free version. To avail the premium service, you have to pay.

Perform a Trial Run on Three Optimization

To select a suitable plug-in for your website, you can run a trial session. This step will let you unleash which one is fulfilling your demands. But from our practical experience, we have observed the following changes:

  1. ShortPixel provides the best compression size, but it loses a bit of original quality.
  2. Optimole offers a great blend of size and dimension. It returns a larger size within a smaller dimension. The above-mentioned plug-in gets easily adapted with the mobile version as well.
  3. Smush is not ready for mobile optimization.

Image Optimization After Uploading to WordPress

We recommend optimization before uploading. But you can optimize your photographs after uploading them as well. These few easy hacks which will make your optimization swift are listed below:

Use Lazy Plug-ins

Usually, when you visit a website, it starts loading with all the contents present there. Heavier contents such as images narrow down the speed in this regard. That’s why the lazy load plug-in tweaks the way the contents work. It lets the lighter features like text, headers load in the first place. In this way, it enhances accessibility.

Image Optimization After Uploading to WordPress


Another option is caching. This step saves your site’s data in a third-party server to make the user’s access more convenient. There are numerous ways to apply caching through coding, plug-ins, and other tools.

Erase EXIF Data

EXIF data is the primary information of an image which provides the details on how and when the image was taken. Generally, this data is stored within your image. It’s not mandatory for web files. So you can remove this EXIF to reduce the burden on your site. For this, you might have to hire a developer.

Avoid Embedding Images

Try to save and upload media files on your website. Redirect links slow down your site badly. This happens because the files are linked somewhere else.
